 ### pbjs.enableAnalytics(config)
 
-Enable sending analytics data to the analytics provider of your choice.
+Enables sending analytics data to the analytics provider of your choice. For a list of analytics adapters, see [Analytics for Prebid](/overview/analytics.html).
 
-For usage, see [Integrate with the Prebid Analytics API]({{site.baseurl}}/dev-docs/integrate-with-the-prebid-analytics-api.html).
+Note that each analytics adapter has it's own invocation parameters. Analytics adapters that are built in the standard way should
+support a `sampling` option. You'll need to check with your analytics provider to confirm
+whether their system recommends the use of this parameter. They may have alternate methods of sampling.
